To determine the visual and anatomical results and survival after combined chemotherapy and whole eye radiotherapy for patients with bilateral Reese-Ellsworth group V retinoblastoma.
A national referral center for retinoblastoma.
Fourteen patients with bilateral Reese-Ellsworth group V retinoblastoma seen between March 1, 1989, and April 30, 1995, were treated.
Patients were treated with chemotherapy (using carboplatin, etoposide, and vincristine) and whole eye radiotherapy (40-44 Gy in 20-22 equivalent fractions). A medical record review was performed to determine outcomes.
Main Outcome Measures:
Survival, eye preservation rate, and visual acuity.
Two patients died, 1 from a primitive neuroectodermal tumor and the other from the meningeal spread of retinoblastoma. Four eyes were enucleated primarily because of severe disease at presentation. Of the remaining 20 eyes, 6 required enucleation. The disease recurred in 4 of those patients, and neovascular glaucoma developed in 2 patients. Of the 12 surviving children, 5 have a visual acuity better than 1/60 in at least 1 eye.
Although most of the treated group V eyes could be salvaged with chemotherapy plus radiotherapy, the resultant visual acuity was often poor.
